This invention relates to door and gate fasteners and has for one of 1ts ob ects to simplify and improve the construction and increase the elficiency and utility of devices of this character. Another object of the invention 1s to provide a device of this character which may be applied to a door or gate and is operative from either side. 1

With these and other objects in View as may hereinafter more fully appear, I have invented the device shown in the accompanying drawings in which:

The improved more particularly upon heavy barn andwarehouse doors, or upon gates, either swinging or sliding,and for the purposeof;illustration is shown,-in Figures 1, 1 and 5, as applied to a conventional barn door, in which the side wall of the barn isindicated at 10,Jthe door frame or door casing at 11, and the door at 12, the latter-11in ed at one side at 13, to thecasing 11. The astener mechanism is supported in a U-shaped casing formed with spaced sides 1415 and one closed end 16 as shown more fully in Figure 2, the sides 14" and 15 bearing upon the opposite faces of the door 12, and the end 16 bearing over the free edge of the door and the lock casing being secured tothe door by bolts 17, as shown in Figure 5. I

Rotative through the door and the sides 14 and 15 of the lock casing is a relatively large turning bolt 18 having a flattened or oblong terminal 19 at one end to support a turning handle 20 which is held in place detachably as by a cotter pin 21. At its other end the turning bolt is formed with an oblong shoulder 22 to support another turning handle 23. The turning bolt 18 may thus be oscillated from either side of the door by manipulating either of the handles 20' or 23.

Attached to the side 15 of the lock casing, next to the end 16, is a clip 24, havingspaced pivot ears 25 at one edge'and upturned at the other edge at 26 and divided to receive the lower convolution of a spring 27 The ears 25 are designed to receive a pin 28 to swingingly support alock bolt by its shank 29, the opposite end of the lock bolt being formed with a keeper engaging projection 30 at one side and a spur 31 at the other side toreceive the outer end of the spring 27, as shown in deviceis designed for use Figure 5. At its upper end the shank 29 of i the lock bolt is extended and formed with a recess 32 and an aperture 33. The lock bolt is provided with a tapered holethrough the spur 31 to receive a tapered pin or stud 31 shown more clearly in Figure 16, and this pin forms a stop to engage the casing and thus limit outward movement of the latch bolt.

'" "illustrated more fully in Figure The lock bolt is also formed with a relatively large aperture 34, while the plate 14 is formed with a depression or pocket adjacent the lock bolt. The aperture 34 is designed to receive the bolt of av locking means, preferably of the padlock form, as indicated at65-in Figure 16. The bolt 66 of the lock 65 seats in the pocket 35 when applied, which .thus serves as a block to prevent the with drawal of the lockbolt. from the keeper so long as the lock is in position. This is an im portant feature of the device, and adds materially to its efficiency. This depression also acts as a guide for the outer tip or, projection of bolt when the chain is withdrawn. By providing this depression, the latch bolt can be retracted "well into the casing Without danger of its being caught as the tip of the bolt simply passes into the depression.

Located upon the door casing 11 is a keeper 36, having a slot 37 to receive the projectionSO or" the lock bolt. The handle 23 is provided with a pin 38, to swingingly support a link 39 the latter having an eye 40 at one end to engage in the aperture 33 of the lockbolt and witha'slot 41 to slidably engage the pin 38. By thisarrangement when either of the handles 20 or 23 is oseillatedin either direction the lock bolt will be moved on its pivot against the resistance of the spring 27, to withdraw the portion 30 of the lock bolt from the keeper 36, to release the doorand' enable "it to swingon its hinges 13 into open position. \Vhen the handle 20 or 23 is released the lock bolt will be returned to keeper engaging po- :sition. Then, when the door swings into closed position, the inclined face 42 of the .lock bolt will cause the bolt to automatically re-engage-the keeper. The inner ends of the "sides 14 and 15 of the casing are out-turned as at 43 to form a guard to the handles 20 and 23, when the latter are in normal position.

Attached to the face of the wall 10 of the barn or other building, is a catch device 44,

3, and including a slo-t 45, to receive theprojection 3001 the lockbolt when the door is in open position, to lock the door in open position, 1 and prevent it from being closed until the handle23 is actuat-ed to release the bolt, as

will beobvious.

=InF-igures 7 and 8 the slight changes necessary to adapt the device to a sliding'door, are shown, and the corresponding parts are provided with the same reference characters.

In this modified structure the handle 23 only is shown to illustrate the fact that one handle may be omitted without detriment to the operation of the device. In the modified structure thelock bolt is formed with a detent 46, andan inclined nOSe 47,'t he detent adapted to engage overone of a pair of-lips 48, forming a part of the modified keeper 49. V i V The end 16 of the U-shaped casing, has a hole on each side of lock bolt slot 34, and a U-shaped guide 50, shown in Figure 10, is riveted to the end 16, the rivets passing through said holes. This guide, when riveted to the lock casing forms a guide for the inclined nose 4'? of the lock bolt.

WVhen the guide and nose 47' enter the keeper 49 the guide bears against one lip of the keeper 49 which causes the nose 47.0flock boltlto slip automatically back into the guide as it slips over the lip on the opposite side of the keeper 49, and at the same time holds the sliding door rigid both lengthwise and sideways, and prevents the lock bolt from becoming disengaged from the lip 1n the keeper except by turning thehandles.

in this modified structurethe lock bolt is formed with terminal hook 59 adapted to engage over a lip 60 in the keeper 61, attached to the door jamb 11. The keeper 61 is tormedwith an inclined face 62, whichthe hook portion 59 bears against when the-door swings into closed position to automatically lock the door, release of the lock bolt being subsequently effected by pulling on the chain In Figures 14'and 15 is shown the changes necessary to adapt the device to simultaneously operate two of the lock boltsonopposite edges of a door or gate. In this modification the bolt 18 islocated midway ofthe door and the handle 58 which corresponds to'th-e handle '23, and is provided .with two pins 59 to which coacting pull rods 60 and Glare attached by rings 62 and 63, and'lead to the lock bolts at opposite edges of the door, a portion of which is represented at 64.

By this arrangement two lock bolts may be actuated by the action of one handle.

To enable the padlock to be applied tothe door at the mostconvenient place, whether it swings inward or outward, I have provided two types of lock bolts and keepers that operate exactly the same in the long casing or the short casing, so if a door swings outward and is to be padlocked on the outside, the lock bolt and keeper shown in Figure 5 is 'used, or it the door swings inward it can also be padlocked on the outside'by using the lock bolt and keeper shown in Figures 11 and 12.
